Charlie and Ellen Sharpe have seen their business, New Horizons Homes, undergo much change in recent years....

"This new modular home is a nice example of our construction."

Sharpe said the 2,300-square-foot structure features six modules, which were built independently off site in Pinckneyville.

"There's no worry about the weather," he said. "Materials are kept dry and there's less chance of theft. It's basically a safer work environment and much more efficient...."

Ellen said structures vary from one to three stories in height. Basically, no size is too small or large.

"It's just an educational process for the general public," she said. "This is the wave of the future. Instead of waiting months to build a house, it can be done in a matter of days. Our sales are up 15 percent from last year and we project a 40 percent jump next year."
